I have planted this fig in my home garden the last Autumn in its permanent [lace in the ground(the bucket is butomless), not long time ago it was thriving and growing happily with new buds and leaves. its been a month since we have heat waves here in my land, although I water it very frequently each 3 days but it  seems like something bad is happening to it, I am not sure if this is the cause of excess water or maybe lack of it or it is because of the heat and the sun burns.
maybe someone have a good advise for saving this tree.
 best regards, sami

Hard to give advice when I don't know where you are? I put my location in my signature below.  Figs are fairly drought tolerant, although they do like water. In ground, hot and sunny it would be hard to over water. I live in Michigan and I water more often than 3 days, sometimes daily if it is hot and sunny.  It has not rained here in 3 weeks, the ground is very dry. i water daily until the next rain at least.
The discoloration is concerning. If it has been there awhile, sunburn is unlikely. It looks like herbicide damage. Another possibility is aphids. Any bugs on the underside of the leaves?  Did you spray anything on it? It is somewhat normal for them to droop in very hot sun. As long as they recover by morning all is well. In this situation with the discoloration it is something else. It does look like over watering too, with light colored to yellow leaves, but in ground hard to believe, unless it's a low spot and when it rains water pools there, then it could be. They like to be moist as long as the soil is well draining. Have you fed it?

Here in Phoenix, Az it has been in the triple digits like 115° average. I have been watering twice a day 6am/4pm with a light watering mostly over the leaves and branches. I deep water with a good soaking at least twice a week. Finally, the sun had turned all of the leaves brown on my 2 year old rdb. I took off all of the brown leaves, it now has new buds all over. As a precaution the pot was moved to receive the eastern sun only,which is about 6 hours. Hope this helps you.

I live in Israel, the temperature outside reached today 102 Fahrenheit.
Drew, you have raised very important questions ! the possibility of having been sprayed by insecticide is possible too, maybe my father have done that accidentally , now I need to ask him about that. but also the possibility of heat burns can be true.
I think am going to continue watering it, also I will wrap it with a shadow net to prevent a large portion of the sun reaching it.
we will see , it hard for me to get an right answer now

it is in a pot or in ground ?
if the pot is too small and soil is turning hot under strong sunshine, then the roots will get cooked. you'd better move it to bigger pots or bury the pots in the earth.

Sami is in Isreal. 

Sami, your tree is suffering from heat stress in that tiny pot.  I recommend repotting it now in a much larger pot or in the ground.  I would do this late at night or early in the wee hours and water every day until the tree is happy again.  Please note, when you repot figs in Summer, the leaves may yellow and fall off.  But they will grow right back in a few days.

I would remove the bucket and put at least 6" of mulch around the base for about two feed radius, in order to trap moisture and water at least every other day if not daily during 100F days. This tree is definitely heat stressed and if the roots are too shallow and trapped within the walls of your bucket they might be baking.

OK more info, location helps. Can you buy shade cloth? To keep it cooler I would install shade cloth to partially block sun (and direct heat). And what Sas says about mulch is very true. Use any organic material you can find. Bark, wood chips, leaves, straw, pine straw, even compost. I like to use compost, then cover with straw, bark, or some other organic material.

If you're not root bound your feeder roots are probably well outside the pots circumference,are you watering the pot only?You might want to think about
irrigating 12"-18" away from the outside of the pot.

Tree looks fine in relation to the heat wave here and the fact that its potted.

You can put in shade.

Btw most my potted trees look like that.

BTW what variety is this? Leafs are interesting.

Hi elin
The tree is not potted as I stated before , the picture is misleading . the pot has no bottom! it holds the water  pretty good around the trunk.  these tree I got from Bassem from treesOfJoy in an exchange deal before  2 years . surprisingly I have another 2 trees from the same variety planted away from this one and they are doing real good , strong and vigorous . tomorrow I will see if I can show you some pictures of them.

My Pete's Honey fig tree is doing the same thing: yellow falling/fallen leaves and dried up new figs. It's been in the ground for over a year. Last Monday the temps went up to around 110 degrees here and stayed high for several days. More of this to come in the months ahead. I'm thinking of digging it up, re-potting it, and moving it to a shady afternoon spot. I'm watering almost daily and you can see the other younger fig trees near by are fine and fruiting. I've left the dead wildflowers at the base which have gone to seed to provide some mulch/protection. 

   

Mara you are a true renegade gardener.

Hi Sami,

Looks to me like it may have dried out a bit because of the heat wave you mentioned. The ground does appear to be dry around it. I agree with the others who recommended using mulch inside the bucket and a little around it (I would keep mulch away and not too deep around the tree). This should keep the top layer moist even if you forgot to water promptly. Also, I would recommend a small moat just outside the bucket to keep the water from running too far 

btw, I have been meaning to write you to thank you for the excellent Khurtmani cuttings. It's hard to believe that in only 12 weeks, one of them is over 3 feet tall and carrying a bunch of figs on it. The second cutting was also quite successful but smaller (the hole I dug was a smaller for the smaller tree). This amazing tree is a testimony to t   he source (you know what I mean). Attached are pictures of both trees. As you can see, I have wood chips around both to avoid drying out in case I forget to water them, although they get a personal visit from me daily :)  
I cant wait till the figs mature
